LINER HOLDER FOBiLINE-TYPE-CASTING MACHINES.

Application filed May 31, 1923-. Serial No. 642,459.

To all whom it may) concern:

Be it known that we, QHARLES F. Enu inns and PAUL Froirnrirrn, citizens the l. i ted States, residing Qaltland and Alemeda, respecti vel i, the county of Ada meda, Calitornimhave invented new and useiulliiner Holder for Line-Typetlastin-g Machines, oi? which the following is a specification in such full and clear terms as will enable those skilled in the art to construct and use the same.

This invention relates to a liner holder tor use in line type casting machines, an object 0t which is to provide means whereby a number of diiierentlength liners may be conveniently produced from a standard pair of liner ends. V

It will be understood by those skilled in the art of line type casting machines, that in the production of lines of different lengths, a liner is placed within the type casting mold to determine the opening length thereby determining the length of the line of type that is cast each time,

These liners are very expensive and a large number of them are required for use with the type casting machines, so that the present invention is intended to take the place oi these liners and provide a conven ient means whereby a liner oi". the desired length may be cast at any time when a change is desired. only a few pairs of liner ends, all of the pairs alike, being necessary to produce liners of the desired length.

It will be understood that while this liner is intended specially tor use with line type casting machines, that it may he used in any machine where variable liners are required.

Other objects of the invention will appear as the description proceeds.

An embodiment of the invention is shown in the accompanying: drawings in which the same reference numeral is applied to the same portion throughout. but we are aware that there may be modifications thereof.

Fig. 1 is a perspective view of one of the line casting molds removed from the machine, illustrating the position of use of this line holder, although, of course, the liner is placed in position without removing! the mold from the machine.

Fig. 2 is a plan view of the liner holder.

Fig. 3 a cross-sectionalview of the same,

5 is a plan view of the: longer liner bl. e liners determining the length of the slug cast.

The cover is secured to the bottom of the mold by screws 6 and 7, and when a liner of a different length is to be placed in the ld, the screws 6 and 7 are loosened enough to permit the. new liner to be slipped into place: in the slot between the cover and bottom of the mold. I

This liner holder comprises a flatbar 10 having dovetail groove 11 to receive and hold a slide 12.

At the opposite end of the bar from the slide 12 there is a fixed plate 13 with a point 1 2-. one edge of which is formed to stand at right angles to the bar 10.

The slide 12 is rigidly connected to a point 15, one edge of which is parallel to the edge 14.. and remains so throughout any adjustment oil the slide 12.

The slide 12 also carries a flat spring 16, which has two rounded portions 17 and 18 to project into the recessed notches of the liner end 19 to hold said liner end in place while the mold is being adjusted. The rear end of the spring extends into a notch oi the plate 10 to make it more secure and to make the spring stronger.

The back portion of the point 15 is split to form the spring 20, which spring carries a pin 21, capable of being inserted in any one at the holes 22 in one edge of the bar 10. The device is held square against the mold when being used with the aid of two depending lugs 10 and 10 secured under the bar 10.

The other edge of the bar 10 is provided with a scale usually reading in ems for the convenience of the printer, the reading being such that the number of ems read will be the distance from the left hand edge of the point 15 to the liner in the right-hand end of the mold, Fig. 2.

In use, the short liner end 19 is inserted between the spring 16 and the point 15 which will hold that liner end at right angles to the bar 10, thereupon the mold cover is slightly loosened, the proper left hand liner end 2 (see Fig. 5) is inserted at the left hand end of the mold and then the bar 10, with the liner end 19 is placed so that the liner end 2 is in its proper place and the liner end 19 is under the cover at the desired distance from the liner end 3, Fig. 1, and this liner end 19 is then tightened against the lower portion of the mold by tightening the screws which hold the cover down.

As soon as the linerend 19 has been tightened in place, in the casting wheel of the type casting machine, the cast is made. This will fill the space between the two liner ends, each of which has frusto-conical recesses, as indicated at 23 and 24 to insure properly securing the type metal to the liner ends. After the first cast has been made a blank of the desired length will be ejected and then the casting will take place in the usual manner, and a line of type of the desired length will be ejected each time.

When it is desired to change the length of the liner, all that is necessary is to remove the liner then in use, break out the type metal from the two liner ends and reinsert the liner ends 2, with the end 19 at the desired distance from the liner end3, whereupon another cast may be made, and a fresh liner will be immediately produced of the desired length.

What we claim is as follows, but modifications may be made in carrying out the invention shown in the drawings and in the above particularly described form thereof, within the purview of the invention.

We claim:

1. An apparatus of the class described, comprising a bar having a projecting point with a face at right angles thereto at one end, a slide movable along said bar, a projecting point carried by the slide, a spring for securing a liner end resiliently against the latter projecting point, and a fiat spring movable vertically to the width of the bar to hold the latter point and the liner end in any desired adjustment along said bar.

2. An apparatus of the class described, comprisinga bar having a projecting point with a face at right angles at one end, a slide movable along the bar, dependinglugson the bar to aid in holding the latter at right angles to the face of a liner mold when placing the liner end in position in the mold, and a spring for holding a liner end against the arm of the movable slide. s

In testimony whereof we have hereunto set our hands this 22d day of May, A, D.
